A refractor type telescope which is a kind of optical telescope, also known as a refractor, utilizes a lens as its goal and purpose to create an image. The design of these types of telescopes was initially utilized in spy glasses as well as astronomical telescope however is also utilized for camera lenses with long focus. Refracting telescope is a tech that has frequently been used in other optical apparatuses like binoculars.
Refractor telescopes are commonly used by many; however there are far more powerful telescopes used by professionals. A super telescope has started the ultimate detailed examination of the Universe ever embarked on. The objective of the programme, which lasts five years, is to know more about Dark Energy, the unexplained force which is believed to drive a hastened enlargement of the Universe.
The mechanism efficaciously holds 5,000 small telescopes wherein every 20 minutes, each of these mini-telescope could picture a galaxy. In only a year, experts will have charted more galaxies than other telescopes in the globe combined.
An enigmatic occurrence, Dark Energy acts against gravity as well as responsible for quickening the universe’s expansion. Although dark energy comprises three-fourths of the universe’s mass-energy, its fundamental nature carries on baffling physicists. It has no actual associations to dark matter, which simply signifies that scientists have no idea what these are.
Discovery of Dark Energy
The awareness that the cosmos is expanding could be drawn back in 1929 to Edwin Hubble, an American astronomer who observed that the more distant a galaxy is from the planet Earth, the quicker it moves away from us, as per the website of the Hubble Space Telescope. This does not denote that the Earth is the epicenter of the cosmos, but instead everything in the cosmos moves away, at a steady rate, from everything else.
Almost six decades after the revelation of Hubble, scientists rendered another astounding discovery. Scientists had been attempting to accurately gauge cosmic distances for so long by studying the light of distant stars. After observing faraway supernovas in the late 90s, two independent groups discovered that the light of the stellar explosions is dimmer than anticipated. This means that the cosmos isn’t only expanding, but is as well accelerating or hastening in its expansion. In 2011, the discovers earned the Nobel Prize in physics.
